Objectives

Narrative objectives1

Although phase-resolved 3D phase-contrast MRI allows non-invasive measurement of hemodynamic parameters in patients with pulmonary arterial hypertension in vivo, enough knowledge is not provided. The aim of this study is 1) to measure the flow parameters including flow velocity and wall shear stress by using MRI in the pulmonary artery in patients with PAH. 2) to evaluate the clinical efficacy of these parameters.
